are you sure you instantiated the appropriate hierarchy for struts to save the form properties into on submit? You can build it yourself, keep it in the session or use LazyBeans (not sure about the last one - might be called LazyNested or similar).

Hi all
I have a problem with setting the values on a hierarchy of nested
properties.
I have an ActionForm which has a property A of type HashMap. A is keyed on
Strings, and each value of A is a Collection (ArrayList). This collection
contains objects of type B.
I am trying to iterate through the keys A, and for each key, iterate through
the corresponding value (which is an ArrayList of B objects), i.e. I am
trying to do 2 levels of iteration. The I want to display a property of B
and let the user change it. I am able to display the properties of object B
on the screen. However, for some reason the <nested:text> tag doesn't work -
the textbox is there, but the input does not populate the form.
The following is what I am trying to do.
<nested:iterate id="idForA" property="A">
<nested:iterate name="idForA" property="value"> <!--this should access
collection of B objects -->
<nested:text property="foo"> <!--allow user to enter a
property of B -->
</nested> </nested>
</nested>
The problem is that when I enter a new value for foo, nothing happens; the
value of the nested property is not set. Is it possible to iterate through a HashMap, and let the user update its values?
I am quite new to Struts, and have spent a lot of time trying to get this to
work, but no luck. Any help will be appreciated!
Thanks
Danielle
